Itertools covers map, filter is covered by genexps.  'reduce' is the
only one that does not have an equivalent anywhere.  I guess we could
cross-link itertools.map into functional.map, but I would rather just
mention in the docs of one that it is located in the other module. 
And filter is just not worth it; that can definitely be covered in the
docs of the module.
